Blender freezes up, after hibernate while Blender is 'Not Responding'
I think you know the answer to this one already. 3D can be one of the of the most computationally intensive activities to throw at a computer. It becomes unresponsive because is busy crunching the numbers to work out your simulation..... Judging by your post, you are indeed pushing your computer to it's limits. Let it do its' job... don't hibernate it... get a book, meditate, go for a walk, interact with other humans. 3D requires a bit of patience sometimes... Once blender has finished is job and your computer is back, bake the simulation and save your file so you don't have to start over
